Abstract: Abstract An arrangement for measuring the position of a part in a machine which is linearly traversible in relation to a fixed part of the machine, such as the position of slides or spindle heads in machine tools, comprising a scale provided on one of the two relatively movable machine parts and reading equipment on the other machine part, characterised in that the reading equipment consists of a plurality of reading devices associated with a scale and spaced at intervals equal to the utilisable length of the scale.  Known arrangement require the length of the scale to be equal to the distance over which the movable part of the machine can be traversed, so that the reading equipment travels along the entire graduated length of the scale.  The diffi-culties of machining the surface of the components of such known machines bearing the graduations of the scale so that they possess the desired parallelism and flatness, and providing sufficient space to accommodate the scales where long scales are required are avoided by the present invention.

Abstract: ABSTRACT OF THE DISCLOSURE           A spray gun is disclosed for simultaneously spraying a liquid and a particulate material, for example, in applying decorative facings to walls and like surfaces.          The gun has a body defining a handle section and a nozzle assembly coupled to the body and having a central opening for the discharge of a stream of said particulate material and liquid discharge means disposed around said opening for the discharge of liquid around said stream of parti-culate material.  The body includes a first air passageway adapted to be supplied with pressurized air and coupled to said central opening of the nozzle assembly.  A second air passageway is also provided and is adapted to be supplied with pressurized air and is coupled to said liquid dis-charge means of the nozzle assembly.  First liquid inlet means is provided for the introduction of said particulate material into the first air passageway.  Second inlet means is also provided, through which said liquid can be introduced under pressure into the second air passageway and the body also includes means for controlling the intro-duction of said particulate material into the first air passageway.  The gun has a trigger mounted on the body adjacent the handle section for progressive movement with respect to said body from a rest position, the trigger being positioned so that it can be squeezed towards said handle section by a person holding the gun by said section.          Spring means is provided normally biassing the trigger to its said rest position. An air flow control valve is disposed in the first air passageway and is coupled to the trigger so that the valve is progressively opened as the trigger is squeezed.  The second inlet means includes a liquid flow control valve coupled to the trigger so as to be progressively opened as the trigger is squeezed. This allows the volume of liquid and the amount of par-ticulate material issuing from the gun to be simultan-eously  varied in use by operation of the trigger.

Abstract: Abstract of the Disclosure A charge couplet device having a meandering charge transfer path is disclosed. The device includes two channel stops each comprising a long band portion from one edge of which project similar short portions.  The channel stops are disposed with their long portions in parallel spaced relation and their short portions interdigitated, thus defining a meandering charge trans-fer path.  An asymmetric depletion layer may be formed in each area of the charge transfer path which is bounded by two adjacent short channel stop portions.  This can be done by varying the thickness of the insulating film over the area or by varying the impurity concentration of the substrate.  A signal can be extracted from a side of the device by providing an outwardly projecting channel portion and this permits the device to be modified for use as a transversal filter or an imaging device.

Abstract: LASHING AND DAMPING ARRANGEMENT   FOR ROTATING TURBINE BLADES     ABSTRACT OF THE INVENTION         A lashing and damping arrangement for minimizing vibrations of the tips of rotating turbine blades.  An elongated lashing wire has hemispherical ball heads securely fastened thereto at each terminus thereof.  The heads are received within corresponding hemispherical sockets, the sockets being mounted adjacent the trailing edge of a first rotating blade and adjacent the leading edge of a second rotating blade, both sockets being disposed adjacent to the radial tip of each blade.  The surfaces between the hemi-spherical balls and the sockets integrally mounted to the blade provides a friction generating interface so that any motion of the tips of either blade in any predetermined direction generates a rolling and a sliding frictional force along the interface to inhibit motion of the blade tips.

Abstract: Abstract of the Disclosure A fluorescence spectrophotometer in which the optical system for the excitation monochromator includes an arrangement for forming an image of the exit slit of the monochromator adjacent a first surface of the sample being evaluated and for forming an aperture image adjacent a second surface of the sample.  Fluorescence from the sample is directed to an emission monochromator which likewise has an arrangement for forming an image of the emission monochromator's entrance slit adjacent a third surface of the sample and for forming an aperture image adjacent a fourth surface.  The optical components are arranged such that the images of the slits lie in a single plane defined by the axial rays of the excitation and fluorescence beams, and in several advantageous arrangements the slit images are oriented at ninety degrees from the slits themselves.  In some cases the optical system includes aspherical mirrors arranged to give different magnifications of the images in the horizontal and vertical planes.  The intensity of the output signal may be further increased by using wedge shaped optical elements adjacent the sample and by  locating mirrors behind the sample holder to direct the light back through the sample for a second pass.

Abstract: ABSTRACT OF THE DISCLOSURE     For fitting a printing sleeve in a printing roll the outer surface of the roll core and preferably the inner surface of the sleeve are made with one end of a lesser diameter than the other; the sleeve is slightly undersize diametrically.  Remote from the ends of the core are orifices whereby gas under pressure may be blown radially outwardly from the core.  The difference in diameter allows the sleeve to be passed freely along the core until it jams up against an increased diameter portion of the outer surface of the roll, at which time it covers the orifices.  Gas is then blown from the orifices to expand the sleeve which can then be moved into its working position on the core. A sleeve specially suitable for this treatment is made by laying-up a seamless GRP layer on a former which is undersize for the designed core and either curing a rubber layer in situ onto the layer, or adhesively securing a flexible plate to a true cylindrical outer surface of the GRP layer.   A transition between the regions of different diameter of the outer surface of the roll core may be made by a frusto-conical taper (preferably of the order of 5 parts in 10,000 to 20,000) or by at least one step (preferably slightly greater than the designed undersize of the sleeve, say 0.008 and 0.006 inches respectively).

ABSTRACT      A creping doctor in which a long, thin blade is applied to a roll surface at an angle to the tangent at the line of contact such that the blade presents a wide surface to the product being removed from the roll.  A preferred angle is less than normal so that the roll surface tangent and the wide blade surface receiving the product make an acute angle.  A bladeholder provides both coarse and fine compliance of the blade to roll surface contour variations.  Blades incorporating resilient means distributed along the back edge for cooperating with the bladeholder are also described.
